Taylor Chandler - who said during her teens she changed her name and used testosterone blockers before having surgery to remove her male genitalia in her early 20s - took to Facebook shortly after the 30-year-old and his girlfriend Nicole Johnson made their announcement.

While Taylor, 40, once described their sex life as “amazing” after claiming they met on Tinder, Michael has never publicly commented.

“Let’s just say he makes Charlie Sheen look like an amateur,” she alleged in the lengthy post, which also accused the swimmer of "destroying" her life.

"One of the hardest things ever for someone dealing with a gender challenge to deal with is an ex having a baby with another woman. It reinforces that lack of self worth, being woman enough. It amplifies that void already felt," she wrote.

"I didn't lie. I didn't date multiple people at the same time. I didn't keep someone hanging on knowing it could hurt them. I didn't make promises I didn't keep. I am the one that lost my privacy, career, and life as I knew it because of one man and his actions. I did absolutely nothing wrong a year ago."

She continued: "He took everything from me, so yes I am bitter. He made me emotionally crippled, broken and a mere shell of who I used to be. After losing my career I did an adult film, not exactly something I ever would have chosen. I was trying to survive. That turned into me riding his coat tails… lol."
